ADAS calibration
ADAS · recalibration · camera alignment · driver assistance
ADAS calibration is the operation that realigns advanced driver-assistance sensors — windscreen camera, radar, blind-spot sensors — after work that changed their position or their reference. Without it, the system keeps operating on a false geometry.

It applies to far more jobs than the counter tends to assume: windscreen replacement, bumper repair, mirror replacement, wheel alignment, sometimes a simple ride-height change. An apparently ordinary part can therefore trigger a heavy technical operation.
For the distributor the effect is concrete: selling an ADAS-sensitive part is not a parts sale, it triggers a job requiring equipment, a calibrated space and time. A workshop that cannot calibrate will decline or subcontract — better known before the reference is proposed.
It is also a liability question: a vehicle handed back with an uncalibrated assistance system is a vehicle whose safety equipment does not behave as designed.
The trap
Selling a windscreen as glazing. On a vehicle with a forward camera, fitting without recalibration leaves an assistance system active but misaligned — the job is not finished.
Frequently asked
Which jobs trigger a calibration?
Any job affecting a sensor's position or mounting: windscreen, bumpers, mirrors, wheel alignment, suspension. The exact list depends on the vehicle and its equipment.
Can calibration be done without dedicated equipment?
Depending on manufacturer and system, some calibrations are dynamic and performed while driving, others require a target and a standardised space. Both cases exist across the same fleet.
